Osmotic and Ionic Regulation in Animals focuses on the processes involved in osmoregulation. The book first discusses general considerations of osmoregulation in animals, including the distinction of body fluids, definitions, and properties of solutions and membranes. The text also looks at the different types of excretory organs, including the differentiation of the excretory organs of mollusks, crustaceans, and vertebrates; protonephridia; and excretion in insects. The selection also describes the ionic regulation in marine animals. Topics include the selective advantages of ionic regulation; mechanisms of ionic regulation; and composition of tissues. The text also discusses osmotic regulation in brackish and freshwater animals. The book also focuses on osmotic regulation in terrestrial animals, including salt gain and loss, secretions, water loss and uptake, and osmotic pressure and composition of blood. The text is a good source of information for readers interested in osmoregulation.

Originally published in 1980, Urban Planning in a Capitalist Society addresses land use planning as both a technical and a political activity, involving the distribution of scarce resources – land and capital. The book reviews and assesses the strengths and weaknesses of several theoretical perspectives, and pluralist, bureaucratic, reformist and Marxist approaches to the distribution of power, and hence resources in a capitalist society. It concentrates on the role played by planning professionals, the opportunity for the public to influence land use planning decision making, and the scope for political action concerning planning.
This timely volume brings together recent critical reviews on water quality requirements for freshwater fish commissioned by the European Inland Fisheries Advisory Commission, an agency of the United Nations Food and Agriculture Organisation. It provides a unique and authoritative source of critically evaluated water quality data concerning the effects of chromium, nickel, aluminium and nitrite on freshwater fish and includes an assessment of the toxicity of mixtures. The reports presented in this volume cover all stages of the life cycle and relevant trophic levels, including aquatic invertebrates and plants and potential bioaccumulation through the food chain. An extensive bibliography is provided for each chapter as well as a glossary of terms and list of fish species mentioned in the text. This compilation of papers is the definitive reference volume for chemists, biologists, ecologists and toxicologists as well as for water resource managers concerned with management and control of pollution in fresh waters."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.

This book covers the major polluting chemicals affecting fisheries in European fresh waters and the effort required to extend the work towards the preparation of critical reviews on less important chemicals would be out of proportion to the benefits obtained.
